Example 2
Referring to fig. 1 to 4, a second embodiment of the present invention is based on the first embodiment: and also comprises the step of performing rough alignment by using a workpiece with higher straightness, such as a straight ruler or a vernier caliper.
Further, the step of making the meter comprises the steps of dividing the couplers into 4 equal parts, making a mark every 90 degrees, and then connecting the two couplers in a semi-linkage manner; and slowly rotating the coupler, recording the reading of each dial indicator every time the coupler rotates by 90 degrees until the coupler rotates to the position of the first reading, recording 4 groups of the readings of each dial indicator, and recording the measured value by using a circular layout according to the position of the read value.

wherein, b is the front foot lifting value of the motor, a is the opening value, Z is the distance between the rear foot of the motor and the coupler, and D is the diameter of the coupler.

wherein D is the diameter of the coupler; y is the distance between the front foot of the motor and the coupler; z is the distance between the rear foot of the motor and the coupler; a is a lower opening value; b, the front foot lifting value of the motor; c is the higher value of the water pump than the motor; d is the coupler lifting value when the rear foot of the lifting motor eliminates the lower opening value a.
Specifically, use the higher work piece of straightness accuracy can adjust the water pump and the motor at shaft coupling both ends to roughly central point at the very first time and put, adjustment volume is unlikely to surpass the measuring range of percentage table during accurate measurement after convenient, also make things convenient for subsequent adjustment work, then divide shaft coupling 4 equally, and every 90 degrees is as a mark, and the shaft coupling both ends can half linkage connection, half linkage state can make the shaft coupling both ends rotate but not a completely fixed state simultaneously, can make the beating between the shaft coupling pivoted in-process show the shaft coupling both ends, help the precision measurement between each position.
Furthermore, 2 dial indicators are respectively arranged on the two ends of the same diameter of the coupler and at symmetrical positions which are equal to the center and close to the edge, 1 dial indicator is arranged on the circumference of the coupler, the dial indicators are arranged on the coupler of the motor or the water pump, the contact of the dial indicators is slightly compressed before measurement, then the reading of each dial indicator is recorded, the coupler is slowly rotated by taking any one of the equal parts of the coupler 4 as an original point and a rotation starting point, the coupler is rotated for 360 degrees, the slow rotation is caused by the generation of rotation errors in the rotation process, if the coupler is rapidly rotated, the needle head of the dial indicator jumps on the contact surface of the dial indicator in the rotation process, if the reading of the dial indicator on the circumference is the same as the initial reading, and if the reading difference of the dial indicator on the measuring end surface is the same as the initial difference value after the whole rotation is completed, if the error is larger than 0.02mm, the reason should be found, and the measurement should be carried out again, the error larger than 0.02mm is the error on the measurement results of the two ends of the current coupler, if the error is not eliminated, the error can be infinitely amplified in subsequent calculation and adjustment, so the data can be recorded when the error is required to be repeatedly adjusted in the measurement process until the error is smaller than 0.02mm, the reading of each dial indicator is totally recorded in 4 groups, the measured value is recorded by using the circular layout shown in fig. 3 according to the position of the read value, the circumferential gap a is recorded outside the circumference, the plane gap B is recorded in the circumference, the measurement record after rotating for one circle is called the actual measurement record, the end surface gap of the actual measurement record needs to be calculated by the following calculation formula:
E1＝(B1+C3)/2 E2＝(B2+C4)/2
E3＝(B3+C1)/2 E4＝(B4+C2)/2 (3)
when the d value is calculated, two situations exist: namely, the value d is larger than the value c or the value d is smaller than the value c, and the final adjustment amounts of the front foot and the rear foot of the motor are respectively set as deltax and deltay.
The first condition is as follows: d is greater than c, Δ x ═ b- (d-c), Δ y ═ c-d, case two: when the value d is smaller than the value c, the value Δ x ═ b + (c-d) and the value Δ y ═ d-c, the expression is that after the opening value of the coupler is eliminated, if the central line of the motor shaft is higher than the central line of the pump shaft, the front foot and the rear foot of the motor need to be correspondingly subtracted by the amount of the increase downwards;
the second case expresses that after the opening value of the coupler is eliminated, if the central line of the motor shaft is lower than the central line of the pump shaft, the front foot and the rear foot of the motor need to correspondingly increase the defect amount upwards.
Specifically, when d > c,
when d < c, the final expressions of Δ x and Δ y can be obtained as well.
(4) The final expressions of delta x and delta y are obtained in (5), wherein D, Y, Z expresses long-reading values, and directional changes do not exist no matter how the mouth opening and the height difference change, namely the +/-numbers of the long-reading values and the long-reading values do not change; in the derivation process, the expression of a is the lower opening value, the expression of c is the higher value of the water pump than the motor, and the two values have directionality. Therefore, it is
The term "a" in (1) is understood to mean the state of the outlet opening, if there is a pump that needs to be calibrated, all values are the same, and only the outlet opening is the outlet opening, and in this case, a' is equal to a
Wherein "a'" expresses the state of the upper mouth. Similarly, c in (4) and (5) expresses a state where the pump is higher than the motor, or the motor is lower, "+ c" indicates that the motor is lower than the pump and needs to be raised.
In summary, the expressions Δ x and Δ y are capable of representing the opening of the coupling and the actual state of the height difference of 0 between the pump and the motor. Specifically, when the coupling is a flare, the first part of the expression should be negative, i.e., have a "-" sign; when the coupling is a flare, the first part of the expression should be positive; when the motor is lower than the pump, the second part of the expression is positive; when the motor is higher than the pump, the second part of the expression should be negative, the opening, the height of the pump and the motor have directionality, and the general expressions of Δ x and Δ y after correction are as follows:
the meaning of the expression here is: the front foot adjustment amount is [ (upper opening value-lower opening value)/diameter of the coupler ]. the distance from the coupler to the front foot of the motor- (excircle-excircle lower);
the back foot adjustment quantity is [ (upper opening value-lower opening value)/diameter of the coupler ]. the distance from the coupler to the back foot of the motor- (excircle-excircle lower part);
the two types are suitable for a dial indicator to be arranged on a pump, and a pointer is arranged on the back of a motor coupling
Wherein: Δ x is the forefoot adjustment; delta y is the rear foot adjustment amount; d is the diameter of the coupler; y is the distance between the front foot of the motor and the coupler; z is the distance between the rear foot of the motor and the front foot of the motor; a is the difference value of the upper opening and the lower opening; c is the difference between the upper part and the lower part of the excircle; the above formula applies to a dial gauge setup as shown in fig. 2 (a).
Then it can be seen that:
the dialgage is erected with the formula shown in figure 2(b) as follows:
the dialgage is erected as the formula shown in figure 2(c) and comprises the following components:
the dialgage is erected as the formula shown in figure 2(d) and comprises the following components:
the universal expression has the advantages that the problems of the upper opening or the lower opening of the coupler, the height of the motor and the height of the pump do not need to be considered in the calculation, the measured numerical value is directly filled in the calculation, the obtained result is positive, the motor needs to be heightened, the obtained result is negative, and the motor needs to be lowered.
